"We have found all the other more important provisions of these contracts as uniformly disregarded. We have torn down and carefully examined the work under more than forty contracts; and we cannot name one in which the work comes up, even approximately, to the specifications. The contracts define with great precision the size and character of the stone to be used, the mode of their disposition, the thickness and other dimensions of the wall, the character of the cement and sand, the quality of lining, and what else is needed to insure durability and a capacity to resist the shocks from loaded boats to which the walls of canals are constantly subjected. In no one of the forty-odd contracts that we examined did we find the stone either in size or disposition; the dimensions of the wall; the quality of the sand, lime, cement, and gravel, to correspond with the specifications. The consequences to the State are not only that it has been called upon to pay for a higher class of work than it has received, but that it is exposed to a large annual expenditure to keep these ill-constructed and for the most part worthless walls in repair. It has been a not uncommon circumstance for the superintendent to be called upon to repair the earlier work under a vertical wall contract while other portions of the structure were still in progress. To keep this class of walls in repair promises to be one of the principal sources of expense for the future maintenance of our canals.[5] [5] See statement of Professors Michie and Wheeler, of the United States Military Academy at West Point, on page 12 of first report of this commission to the Governor. "Nor is this system of fictitious estimates confined to vertical wall. Since 1868 fifty-three and two-thirds miles of slope wall have been built. By the terms of the contracts these walls should have had an average thickness of at least fifteen inches, measured perpendicularly to the slope. None of the stone composing it should have been less than twelve inches in length at right angles to the face, and the rear of the wall was to rest on a base of clean, hard gravel nine inches thick. The engineers have uniformly estimated these walls at the specified thickness of fifteen inches, while in point of fact we have not found on any of our canals a single stretch of slope wall, constructed since 1868, that would average over ten inches. Of course, the stones are usually smaller than the minimum size required by the specifications, and we did not find a single specimen of the clean, hard gravel lining required by the contract; so that the State has been made to pay, throughout the whole forty-three and two-thirds miles of slope wall, for one-third more of constructed wall than it has received--full prices for a very inferior quality of stone--and for lining the whole work, though not a single yard of the required quality appears to have been ever furnished.
